The Mets will consider most options heading toward the Aug. 1 non-waiver trade deadline, but their primary target is another bullpen arm.

Of course, the Mets still may need another bat, and the rotation is missing a piece — at least in the short term — with Matt Harvey finished for the season with thoracic outlet syndrome, but team brass views another dependable reliever as the most obvious need at the moment.

That reliever, according to a club source, doesn’t necessarily have to be a higher-end option in the mold of Tyler Clippard, whom the Mets acquired for the stretch run last year. But names such as San Diego’s Ryan Buchter and Brad Hand could appeal to the Mets, along with Oakland’s John Axford and Atlanta’s Chris Withrow.

If the Mets wanted to make a play on another team’s closer, Milwaukee’s Jeremy Jeffress could be a possibility.

The fact the Mets had no real discussions with the Padres before they traded Fernando Rodney to the Marlins may indicate they are seeking a less splashy move that could provide an arm to complement Hansel Robles and Jerry Blevins, among others, in the seventh inning.

The Mets appear content to piece together the fifth spot in the rotation with Logan Verrett — and perhaps rookie Gabriel Ynoa if Plan A fails — until Zack Wheeler returns from Tommy John surgery rehab, presumably in the middle of next month. But if Wheeler were to incur a setback between now and the trade deadline, team brass still could change course and look for another starter.

But that search for a starter wouldn’t preclude the Mets from pursuing another bullpen arm.

The Mets have a top-notch setup/closer combo in Addison Reed and Jeurys Familia and like what they have received from Blevins and Robles, but there are questions beyond that. As it stands, Erik Goeddel, Antonio Bastardo and Seth Lugo are the final three pieces of the bullpen.

No one has been a bigger disappointment than Bastardo, who signed a two-year contract worth $12 million with the Mets last January. The veteran lefty will enter the second half with a 4.91 ERA and 1.45 WHIP in 35 appearances.

Josh Edgin has pitched effectively at Triple-A Las Vegas, according to a talent evaluator, but the Mets might have concern his fastball velocity has topped out in the low 90s. Before undergoing Tommy John surgery last year, Edgin regularly brought 95-mph-plus heat.

The Mets traded stud pitching prospect Michael Fulmer at last year’s deadline to acquire Yoenis Cespedes from the Tigers, but have few high-end prospects left.

Amed Rosario, who could be playing shortstop at Citi Field by the end of 2017, appears off limits and the club has no plans to deal first baseman Dominic Smith — who joined Rosario at the Futures Game in San Diego this week.

Anthony Kay, the Mets’ second pick in the June draft, agreed to terms with the club. The lefty pitcher from Long Island — a former UConn standout — will receive a $1.1 million signing bonus, an industry source confirmed.
